Executive Summary

We assess that the border between Canada and the US does not pose a significant security threat to the US. This is despite past security incidents. While its vast size makes comprehensive monitoring nearly impossible, the data suggest that Canada is a relatively small channel of illegal immigration and synthetic drugs entering the US. 

The tensions around the northern border have risen in recent weeks. This happened after US President Donald Trump declared a national emergency at the southern border with Mexico and planned to introduce 25% tariffs on all Canadian imports. He cited national security issues such as the flow of illegal immigrants and fentanyl, through these borders as reasons for his actions. As for the border with Canada, the data contradicts these claims. [source, source]
